GP's just don't "cut it" when it comes to prescribing the medications used for psychiatric disorders, even mild depression, the quickly scribble out one of the various SSRI's and send the patient on their merry way. One needs care from a doctor whose expertise is in psychiatric disorders, people also need to remember this man is an MD also,but has years of additional training.etc. too! Personally I believe a person should seek the kind of doctor most suitable for that particular ailment. Some people that are depressed or fell they have mental disorder sometimes feel ashamed about it and go to their GP with hopes of skirting the reality, the doc may give you a script for some medication, but he really isn't qualified to work with you through this and he may even not know the proper medication to give you. . . stick to the right doctor for the right disorder, that is my personal opinion.
Best of luck,
